  7.   ADMINISTRATION AND TRAFFIC


  7.01   Data contained in the DMS system is modifiable via the Data
  Modification System.  The modifications of  the data may  be input
  either manually  via a Visual  Display Unit  (VDU) or in  bulk via
  magnetic tape.

  7.02    Peg counts  and usage  measurements  of a  large group  of
  traffic sensitive items of the DMS office are accumulated for half
  hour  periods.  The  sets  of data  on  the  accumulators  may  be
  transferred to magnetic tapes or VDU for traffic analysis.

  7.03   Individual  groupings of  data are available  on VDU  via a
  query system.  The  queries cover such items as  status on various
  groups of  equipment, traffic  data collected  during the  current
  accumulation interval, rating information, and individual line and
  trunk  information.  These  data  provide  material for  compiling
  statistics   concerning  areas   such  as:   analysis  of   switch
  performance, division of revenue, provisioning requirements, etc.
